True PCB removal is complex and must follow regulated processes. Approaches include sending oil to licensed facilities for dechlorination, specialized chemical treatment, or high temperature destruction, depending on the jurisdiction and PCB concentration. In some cases, contaminated oil is removed and replaced, and the transformer may be decontaminated or disposed as PCB equipment. Filtration alone does not reliably remove dissolved PCBs. Safe handling requires PPE, sealed containers, spill prevention, strict labeling, chain of custody documentation, and compliance with hazardous waste transport and disposal regulations.
